GT-POWER is the industry leading engine simulation tool used by every major engine manufacturer worldwide.
Engine simulation, sometimes referred to as cycle simulation, is a mainstream activity conducted
by all engine manufacturers. Within this activity, GT-POWER is used to perform a variety of both
steady state and transient analyses.
Steady state studies often include:
- Torque, power, and volumetric efficiency curves for SI and DI engines
- Turbo/super charged engine performance, lug line, turbo matching
- Engine downsizing studies
- Variable geometry systems
- VVT and VVL specification
- Intake and exhaust system acoustic characterization
- Injection rate shaping for minimum NOx, minimum bsfc
- Exhaust aftertreatment concept studies
- Cylinder pressure analysis
Transient studies include:
- Tip-in / Tip-out response
- Turbocharger response (turbo lag studies)
- A/F ratio response (wall wetting)
- Intake and exhaust system drive-by noise levels
- Control system analysis
Through the library of dedicated engine modeling elements available in GT-POWER, engineers may
quickly build up models of engines of all types, from the simplest conventional engine to the
most sophisticated, novel concepts (including for example, the GOMECYCS concept and free piston engines).
Base engine models are built via drag and drop of dedicated engine modeling elements in the GT-SUITE
preprocessor. Construction of more complicated geometries (mufflers, resonators, plenums) is aided
via GT-SUITE's built-in 3D, CAD based preprocessor tools, which allow the user to build models in a
3D environment, including importation of direct CAD data as a starting point. Result interpretation
is aided via the built-in post-processors, including a response surface fitting tool that enables rapid
optimization and design exploration studies to be conducted on an a posteriori basis for maximum
productivity.
